How Air Exchangers Work


How do I set up the dehumidistat control?

basicAn adjustable dehumidistat control feature is available on the following vanEE wall controls.

  • BASIC central wall control
  • BRONZE central wall control
  • Dehumidistat remote wall control

To adjust the set point, the control knob is turned counter-clockwise when higher indoor humidity levels are acceptable and conversely, the knob is turned clockwise when lower indoor humidity levels are needed.

The dehumidistat feature will engage the HRV or ERV's high speed ventilation whenever the control senses that the humidity level is above its setpoint. When the indoor humidity level is less than its setpoint, the HRV or ERV will operate or not operate according to how other system controls (either mounted on the unit or remotely mounted) are set.

During the heating season(s) an ERV or HRV is not a humidifier, both will reduce the indoor humidity level. An ERV reduces the indoor humidity less than an HRV. Generally, the dehumidistat should be set as high a level as possible while still keeping windows clear of condensation.

This is a trial-and-error process. Turn the knob up to 70% and see if condensation ever occurs. If there is no condensation, leave it at this setting. If condensation does occur, then turn the knob to a lower setting (clockwise) until you hear a “click” sound from the control. Leave it at this setting and see if over the next day, the condensation disappears.

If condensation still occurs, then again turn the knob to an even lower setting until the “click” is heard and wait a day. Repeat as described above until there is no longer condensation. If no “click” is heard when turning the knob counter-clockwise then the unit should be already running at high speed ventilation (check this) and turning the knob lower will not increase the dehumidification capacity of the HRV or ERV. Check that you have the correct type or size of unit for your application.

During the cooling season(s), an ERV or HRV is not a dehumidifier, both will increase the indoor humidity level when a house is air conditioned. An ERV increases the indoor humidity less than an HRV. Generally, the dehumidistat should be set at the highest level possible during the cooling season (knob turned fully counter-clockwise.).
